Data Characteristics

StockCharts uses a three-step process to calculate breadth indicators. First, StockCharts maintains component lists for these indices. Second, our scan-engine uses these component lists to run scans based on the price data for the individual stocks. Third, the data is then updated and published to our website.

This “in-house” data may differ from other sources due to differences in the index components and price data. Index components change and require updates on a regular basis. Also note that StockCharts uses dividend-adjusted data for its calculations, while other sources may use non-adjusted data.

Definition

Advance-Decline Volume Percent (AD Volume Percent) is a breadth indicator that measures the percentage of Net Advancing Volume for a particular group of stocks, such as an index or ETF. Net Advancing Volume equals the volume of advances less the volume of declines. AD Volume Percent equals Net Advancing Volume divided by total volume for the group. AD Volume Percent fluctuates between -100% and +100%. Chartists can use this indicator to create oscillators and the AD Volume Line.
